According to a recent Nestle ad campaign aimed at parents, a drink called Boost Kid Essentials was so good for children that it could keep them from getting colds and missing school.

But on Wednesday, the Federal Trade Commission said the ads were deceptive and announced that Nestle had agreed to stop making the claims.

The move was the second in two months aimed at deceptive advertising by a major food manufacturer for products meant for children. A commission official said that the agency was taking a close look at the proliferating number of health claims made for all types of products on supermarket shelves.

“Food companies are marketing more of what they call functional foods,” said Karen Mandel, a staff lawyer for the trade commission. The term refers to foods with added nutrients that companies claim can bring health benefits to people who eat or drink them.

“If the claims are not substantiated, that’s what we’re looking for, to make sure the claims are truthful,” Mandel said.

The action Wednesday involved Boost Kid Essentials, a nutrient-laden beverage made by Nestle HealthCare Nutrition that comes with a straw containing probiotic bacteria, which is similar to the live cultures in yogurt. Many people say they believe that probiotic bacteria aid digestion and provide other benefits.
